At 75, George Soros, one of the most controversial billionaires -- his critics in the United States call him Red George because of his consistent support for liberal and leftist causes -- does not have the slightest desire to slow down.

On the fifth anniversary of 9/11, he is ready to travel across America to promote his new book The Age of Fallibility. He is also planning to visit India and share his thoughts on promoting open societies with transparent politics with non-governmental organisations and individual activists.

The Hungary-born businessman has written that 'America must undergo a change of heart' regarding its fight against terrorism, also asks fellow Americans to reject the war of terror that has been promoted by US President George W Bush but backed by millions of people of different political persuasions.

The founder of a global network of organisations active in more than two dozen countries, Soros funds associations connected to liberal causes including the abolition of the death penalty.

He is "an enlightened philanthropist who knows how to put his billions to the best use," says Nobel Laureate Amartya Sen, "I have the highest regard for him, and I read his books and benefit from them."
